At one point in the film, King Edward VIII makes fun of Prince Albert's stammer by saying: "Younger brother trying to push older brother off the throne. P-p-p-p-p-positively medieval!" Minus the stammer, this was an actual line written by the real King Edward on his brother when he was away from Great Britain for a time, having given a few responsibilities to Prince Albert in his absence.

The Kings of Great Britain are played by an Irishman (Michael Gambon plays King George V), an Australian (Guy Pearce plays King Edward VIII alias Duke of Windsor), and finally an Englishman (Colin Firth plays King George VI).
